中文摘要：

通过构建行业收入差距与经济社会发展（经济增长、资源配置效率、分配公平、社会稳定）两大类指标体系，运用行业收入差距适度性的测度方法，测算长三角地区行业收入差距与经济社会发展的适度性。结果表明：长三角地区两省一市的行业收入差距总体上呈现不断扩大的趋势，近几年稍有缓和；浙江省行业收入差距扩大幅度最大，上海市次之，江苏省最小；从静态适度性来看，两省一市行业收入差距与经济社会发展四个方面呈现优质适度状态，浙江省适度性最高，说明长三角地区行业收入差距还未触及社会容忍度；但从动态适度性来看，两省一市行业收入差距与四个方面的适度性均在逐渐恶化的轨迹上运行。在此基础上提出了缩小行业收入差距的相应的政策建议。

英文摘要：

By constructing the two indicator systems of the industry income gap and economic and social devel opment （economic growth, efficiency of resource allocation, distributive justice, and social stability）and, using a moderate measurement of industry income gap, the researchers in this paper measured the income gap and the eco nomic and social development appropriateness in the Yangtze River Delta with the. The research results showed that the industry income gap in the Yangtze River Delta shows a trend of widening, but alleviated slightly in recent years, with gap widened most in Zhejiang Province , Shanghai secondarily and Jiangsu least. From the view of static appro priateness, the industry income gap and the economic and social development in two provinces and one city are in the state of quality appropriateness, but from the view of a dynamic one, this appropriateness shows signs of deterio ration. On this foundation, we proposed the relevant policy recommendations to narrow the industry income gap.
